Men's thermal underwear

Men's functional underwear to keep you warm

Thermal underwear for men represents a real revolution for outdoor sports enthusiasts who are exposed to extreme temperatures, especially when it comes to winter sports such as skiing.

Equipment that keeps you warm

One of the main advantages of this type of equipment is its excellent thermal insulation. In a few words, you'll be sure to maintain your body heat, even in cold weather and at altitude. Made from synthetic fibers or merino wool, your thermal undergarment will help you cope with even the most extreme cold snaps.

Stay dry during intense outings

Your underwear wicks sweat away perfectly, thanks to intelligent body mapping technology, so you're free of moisture and perspiration during intense, physical outings.

Breathable fabric

If it's unpleasant to be cold, being too hot isn't optimal either. That's why you need breathable underwear that retains only the heat you need for comfort.

When it comes to technical underwear, you'll find both performance and design in our online store. If these are worn under other layers of clothing, they still need to be chosen with care.

The comfort of thermal underwear

In addition to thermal insulation, your underwear must also be as comfortable as possible, and fit you perfectly. Since every man is different, it's important to pay attention to the details of your outfit, starting with the fit. At Decathlon, we offer fitted men's cuts that minimize the risk of unpleasant chafing. Note also that our Seam 0 technologies limit the presence of seams, for greater comfort. What's more, a body-hugging design makes it easy to layer garments.

With the same objective of guaranteeing optimum comfort, you can opt for a set of undergarments made from an elastic material with stretch mesh, offering you optimum freedom of movement.

Finally, for the ultimate in practicality, the underwear models featured in our online store are easy to care for, so you can keep them season after season.
